This MBA project investigates the impact of the Performance Management System (PMS) on employee performance within the Jamaica Constabulary Force (JCF) in Jamaica's public service. The study uses four research questions to explore how performance appraisal affects employee productivity, the relationship between productivity and appraisal, the information employees need to understand their work, and methods for improvement based on past performance. Employing a descriptive research design, the study surveyed staff members of the JCF and analyzed the data using SPSS to determine frequencies and rates, presented in tables and diagrams. Key findings reveal a perceived need for a robust PMS with staff input, fair monitoring, and rewards for high performers, alongside improved communication and transparency. The research suggests that the 360-degree feedback system is the most suitable PMS for the JCF, emphasizing the importance of employee perceptions in achieving organizational goals. The study recommends improvements in various parameters related to employee perception, regular performance management, appropriate work design, staff support, and clear communication of organizational policy.
